1. Field of the Invention
The present invention relates to sliders for reclosable pouches, and more particularly, to a pouch having a slider capable of occluding and deoccluding a closure assembly.
2. Description of the Background of the Invention
A pouch for the storage of items typically has a closure assembly disposed at, or adjacent to, a mouth of the pouch. In some cases, a slider is provided on the closure assembly to open and close the pouch. Such closure assemblies have a slider having a top wall and two depending side walls, with a middle section of both side walls creating a concave portion. The top walls of some sliders also have a rectangular aperture disposed therein. Other types of closure assemblies have a sliding clasp having a generally U-shaped cross-section. The sliding clasp has a bight and two opposing side walls depending therefrom. The side walls also have serrations on an exterior surface thereof for assisting a user in gripping the sliding clasp. The top wall of other sliding mechanisms has a central open aperture that divides the top wall between a first portion and a second portion. The first portion generally has a flat, planar portion that extends from a periphery of the open aperture to a closing end of the slider. Similarly, the second portion generally has a flat, planar portion that extends from a periphery of the open aperture to an opening end of the slider. Each of the first and second portions has a groove. The two side walls are parallel to each other adjacent the closing end of the slider and diverge from each other adjacent the opening end. The two side walls also form convex portions in a middle section of the slider wherein the side walls in the middle portion also has vertical grooves separated from one another by lands. Other closure sliding assemblies also have ornamental designs for closing the pouch.
Other closure mechanisms have a slider that has first and second rib members integral with and extending along the exterior of a top and side walls, wherein the first rib member is disposed toward a closing end and the second rib member is disposed toward an opening end. The ribs increase the rigidity of the top and side walls to increase the force required to remove the slider from the closure mechanism.
Still other sliders with a top wall and two depending side walls have a first groove in the top wall adjacent to an opening end of the slider and a second groove adjacent a closing end of the slider. Each side wall includes a rectangular recess disposed in a middle section thereof, wherein four ribs are disposed in each of the recesses.
According to one embodiment of the present invention, a slider for a reclosable pouch includes at least one top portion with at least one top potion having a plurality of apertures. Alternatively, a plurality of apertures may be created from at least one top portion of the slider. The slider also includes side walls depending from opposite sides of the top portion for receiving a closure assembly of the reclosable pouch therebetween. The side walls extend between opening and closing ends of the slider.
According to another embodiment of the present invention, a slider for a reclosable pouch includes a top portion comprising a lattice-like arrangement of ribs, wherein a plurality of apertures is provided between the ribs. The slider also includes side walls depending from opposite sides of the top portion for receiving a closure assembly of the reclosable pouch therebetween. The side walls extend between opening and closing ends of the slider.
According to yet another embodiment of the present invention, a slider for a reclosable pouch includes a top portion comprising a lattice-like arrangement of ribs, wherein a plurality of apertures is provided between the ribs. The slider also includes side walls depending from opposite sides of the top portion for receiving a closure assembly of the reclosable pouch therebetween. The side walls extend between opening and closing ends of the slider and at least one of the side walls includes a concave portion.
According to a further embodiment of the present invention, a slider for a reclosable pouch includes a top portion comprising a lattice-like arrangement of ribs, wherein a plurality of apertures is provided between the ribs.

In still another embodiment, the first and second closing members are on opposite side walls of the slider, while in yet another embodiment, the first and second closing members are on the same side of the slider. The slider may also include at least one foot extending inwardly from a bottom portion of at least one side wall and/or interior portion of the slider of the slider. The feet may be configured to engage the closure assembly to assist or prevent removal of the slider therefrom. The opening end of the slider may include a separating end portion that circumscribes the closure assembly creating a void defined between a majority of the separating end portion and the closure assembly. At least one separating finger may extend inward from a top portion of the separating end portion. At the top portion of the slider the plurality of apertures in one embodiment is a lattice-like arrangement comprising a plurality of ribs. The slider of the present invention may also contain at least one central elongate rib that extends along a length of a top of the slider, including, for example, extending partially the entire length of the slider from the opening end to the closing end or extending substantially the entire length of the slider from the opening end to the closing end. A plurality of ribs may in one embodiment extend transversely from at least one central elongate rib along the top portion. The slider of the present invention may also have at least one top portion, at least one bottom portion, and/or at least one side wall that are not planar.
In yet another embodiment of the present invention a slider for a reclosable pouch has a top portion with a lattice-like arrangement of ribs. A plurality of apertures is provided between the ribs, and two or more side walls depend from opposite sides of the top portion for receiving a closure assembly of the reclosable pouch therebetween. At least one of the side walls may include at least one concave portion or U-shaped side member, and a first guide member may extend inwardly from an inner wall of a first side wall and a second guide member may extend inwardly from an inner wall of a second side wall. A first closing member may also extend inwardly from an inner wall of a first side wall and a second closing member may extend inwardly from an inner wall of a second side wall. In one embodiment, two or more concave portions or U-shaped side member are on opposing sides of the slider. In yet another embodiment, the first closing member and the second closing member are on opposing sides of the slider. In another embodiment, at least one concave portion may extend inwardly partially or substantially the entire length of the slider between the opening and closing ends of the slider. Illustratively, the concave portion or U-shaped side member is formed to allow at least one finger of a user to engage therewith. A concave portion or U-shaped side member may include at least one rib extending thereacross. At least one rib on a concave portion of a first side wall may also extend across the top portion to a rib on the concave portion of a second side wall.
A slider of the present invention may also have a top portion having a lattice-like arrangement of ribs where a plurality of apertures are provided between the ribs; two or more side walls that depend from opposite sides of the top portion for receiving a closure assembly of the reclosable pouch therebetween; and at least one side wall that includes a discrete panel. A first guide member may extend inwardly from an inner wall of a first side wall and a second guide member may extend inwardly from an inner wall of a second side wall.

At least one rib on the discrete panel of a first side wall may also extend across the top portion to a rib on the discrete portion of a second side wall.
A reclosable pouch incorporating a slider of the present invention in one embodiment includes techniques for preventing the slider from sliding off the end of the pouch once the slider reaches the end of the pouch. Illustratively, the techniques for preventing the slider from sliding off the pouch includes, for example, crushing and/or fusing (for example, by heat, chemically, and/or ultrasonically fusing or welding plastic part together) a section of the closure assembly to form a stomp to prevent the slider from passing past the crushed or fused section. In one embodiment, such crushed or fused sections are proximate to the opened position and/or the closed position of the closure assembly.
Illustratively, as a slider of the present invention moves along a closure assembly from an open position to a closed position, the slider configures fastener strips and fastener mechanisms to an interlocked position so as to close a reclosable pouch opening or mouth. As the slider moves along the closure assembly from the closed position to the opened position, the slider configures at least one of the fastener strips and/or fastener mechanisms to an unlocked or disengaged position so as to allow access through the opening to the pouch interior. Stomps and/or stops adjacent to the ends of the fastener strips interfere with and prevent travel of the slider beyond the fastener strips.
A slider of the present invention may be constructed from, for example, multiple parts and joined together, and/or the parts may be constructed to be snapped together. Alternatively, the slider may be constructed from one piece. The slider may be made using any desired method known to those skilled in the art, including, for example, injection molding. A slider of the present invention may be made from any suitable material including, for example, metal, ceramic, glass, rubber, and/or a polymer or a plastic such, for example, nylon, polypropylene, polystyrene, acetal, toughened acetal, polyketone, polybutylene terephthalate, high density polyethylene, polycarbonate, and/or ABS, and combinations thereof.
A reclosable pouch useful in the present invention may be made by various techniques known to those skilled in the art including those described in, for example, Geiger, et al., U.S. Pat. No. 4,755,248. Other useful techniques to make a reclosable pouch of the present invention include those described in, for example, Zieke et al., U.S. Pat. No. 4,741,789. Other useful techniques to make a reclosable pouch of the present invention include those described in, for example, Porchia et al., U.S. Pat. No. 5,012,561. Examples of making a reclosable thermoplastic pouch as described herein include, for example, a cast post applied process, a cast integral process, and/or a blown process. Illustratively, a reclosable pouch wall of the present invention may be made of any flexible material suitable for packaging a sample, article, and/or substance, including, for example, any suitable thermoplastic film. A flexible material useful in the present invention includes, for example, polyethylene (for example, low density polyethylene, and linear low density polyethylene), substantially linear copolymers of ethylene and a C3–C8 alpha-olefin, polypropylene, polyvinylidene chloride, polyvinyl chloride, vinyl, and/or other polymers, in single or multiple layer, and combinations thereof. Additionally, the reclosable pouch wall may be constructed of paper and/or a flexible metal, including, for example, aluminum foil or sheets. The flexible material may be transparent or semi-transparent (to permit viewing of the sample, article, and/or substance in the reclosable pouch), translucent, lucent, clear, and/or opaque, at least in part, depending on the application in which the reclosable pouch will be utilized.
In yet another aspect, the present invention provides a kit comprised of a slider and a reclosable pouch. The slider of a kit may, for example, be configured to attach to a closure assembly by snapping at least on piece of the slider together on a closure assembly disposed on the reclosable pouch. Alternatively, the slider of a kit may, for example, be one piece that is slid onto one end of closure assembly of this reclosable pouch and then, in one embodiment, at least one of the ends of the closure assembly are closed, crushed, and/or fused to form at least one stop or stomp to prevent the slider from passing past the closed, crushed, and/or fused section. The kit may also include a set of instructions to instruct a user how to assemble and/or use the kit.
It is also contemplated that more than one slider of the present invention can be used on a closure assembly and/or a reclosable pouch.
Although the embodiments shown herein illustrate a reclosable pouch opening, closure assembly and/or associated structures at an upper end or top of the reclosable pouch, the present invention is intended to cover other arrangements in which, for example, the pouch opening, closure assembly and/or associated structures are provided on at least one side of the reclosable pouch and/or on at least one bottom portions of a pouch.
The present invention provides apparatuses, methods, kits, and combinations, useful for opening and/or closing a pouch with a sliding closure assembly. For example, the present invention provides sliders exhibiting improved performance as closure mechanisms including, for example, improved performance in opening and/or closing a reclosable pouch, and/or retaining the position of the slider on a closure assembly. The sliding closure assemblies of the present invention also exhibit improved ease of use, while reducing and/or minimizing the amount of material required to make or produce a slider assembly.
The invention has been described in an illustrative manner, and it is to be understood that the terminology used is intended to be in the nature of description rather than of limitation. All patents and other references cited herein are incorporated by reference in their entirety. Many modifications, equivalents, and variations of the present invention are possible in light of the above teachings, therefore, it is to be understood that within the scope of the appended claims, the invention may be practiced other than as specifically described.
